ALOIS ANTHOY, OF BALTIMORE, MARYLAND.

WOODWORKING MAGHIN E.

Application filed February 7, 1922. serial No. 534,652.

To all 'whom t may concern:

Be it known that I, ALoIs ANTHoNy,

a citizen of the United States, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inWoodworking Machines, of which the following is a specification.

This invention relates to improvementsy in wood-working machines, andhas for its object to provide a cheap, simple and eilicient machineespecially adapted for sawing by foot power.

The invention consists of the novel construction and arrangement of theparts and combination of parts hereinafter more fully set forth in thefollowing specification and pointed out in detail in the appendedclaims.

In the accompanying drawing,-

Figure 1 is a Aside elevation of my invention.

VFigure 2 is a top plan view of Figure 1.

Figure 3 is an end view of Figure 1.

Referring to the accompanying drawings, 25 forming part of thisspecification, and in which like reference numerals designate like partsthroughout the several views thereof,

1 designates the table frame whichis provided with an adjustable table 2having one end hinge-d at 3 and a screw 4. at the opposite end to raiseand lower the table 2 with respect to the saw 5. The said saw 5 ismounted on the shaft 6, the latter being mounted in the bearings 7 and8. The opposite end of the shaft 6 is provided with a pulley 9 connectedby the belt 10 with the wheel 11 on the shaft 12. The said shaft 12 ismounted 4in the bearings 13 and has a wheel 14 on its opposite end ofthe same size as the wheel 11. 'Ihe rods 15 are pivoted at one end tothe table frame 1 at 16 and are connected at their opposite ends to thewheels 11 and 14 by the bolts 17 which eX- tend through the elongatedslots 18 in said rods 15. The treadle 19 has two side pieces 20 whichhave their ends pivoted to the links 21 which latter are in turn pivotedto the table frame 1 at 22. A rod 23 extends through the rods 15 andsi-de pieces 2O of the treadle, and also through the end of the arm 24.The said arm 24 projects through the bearing 25 and has a coiled spring26 connected to one end and an adjustable weight 27 at the opposite end,both of which serve to return the arm 24 to its normal position.

When the treadle 19 is pressed down against the action of the spring 26and weight 27, the rods 15 are also forced down causing the wheels 11and 14 to revolve, and power is transmitted from the wheel 11 throughthe belt 1() to the shaft 6, causing the saw 5 to be revolved. When thetreadle 19 is released it will be returned to its normal position by theaction of thespring 26 and weight 27, and the same action repeated, thuscausing the continuous revolution of the saw 5. Y

Having thus described my invention, what I claim is:

l. A mechanical movement comprising a frame, a shaft revolubly mountedin the upper part of said frame, two wheels mounted in said frame, atreadle having one end pivoted to said frame, two rods each pivoted atone end to said frame and to said treadle and having elongated slots intheir upper ends, bolts passing through said elongated slots of saidrods and connecting them with the said wheels, and means connecting oneof said wheelsy witli.said shaft for operating the latter.

2. A mechanical movement comprising a frame, a shaft revolubly mountedin the upper part of said frame, a treadle having one end pivoted tosaid frame, two rods each pivoted at its lower end to said frame and tosaid treadle and having elongated slots in their upper ends, boltspassing through said elongated slots of said rods and connecting thesaid rods with said wheels, means connecting one of said wheels withsaid shaft for operating the latter, an arm mounted in said frame andpivoted near one end to said treadle, a spring connecting one end ofsaid arm with the frame, and an adjustable weight on the opposite end ofsaid arm.

In testimony whereof I affix my signature.

ALOIS ANTHONY.
